I never heard that islam hates people
I have personally hear a teaching to hate non muslims from a salafi live internet group lesson.
But there was a salafi sectant teacher.
And did you report this hate preaching teacher to the authorities - my guess is no.
And thats the problem with muslims - they arent prepared to clean their own house and when the radicalized go on a killing spree its never Islams fault as they arent proper muslims.
The sooner the next crusade kicks off the better, every muslim needs to be eradicated from the planet.
